  • [Windows] How to Jailbreak iPhone 3G Firmware 3.0 with RedSn0w
    This guide will teach you how to Jailbreak your iPhone 3G running 3.0 firmware using RedSn0w on Windows. You can unlock your iPhone 3G AFTER following this guide by using UltraSn0w. Directions on that are here. Anyways, lets continue.

    I strongly recommend you backup and restore your iPhone 3G to 3.0 firmware via iTunes BEFORE you begin this guide. By strongly recommend I mean restore to 3.0 firmware.

    You will need RedSn0w 0.7.2 which you can download here along with the iPhone 3G 3.0 firmware file available for download here.

    Once you have downloaded everything, extract redsn0w-win_0.7.2.zip to a location on your computer. You should see redsn0w.exe. Run it.

    Click Browse.



    Browse to where ever you downloaded your iPhone 3G 3.0 firmware .ispw, select it, and click Open.



    RedSn0w tells you that the ISPW has been successfully identified. Click next.



    You'll see a little window that says patching kernal for a second.



    Select Install Cydia and click Next.



    Plug in your iPhone 3G and turn it off. Once it is off click Next.



    RedSn0w gives you instructions. We are entering DFU mode now. First hold the power button for 3 seconds.



    Keep holding the power button and start holding the home button for 10 seconds.



    Release the power button but continue holding the home button for 30 seconds.



    RedSn0w does its thing. Let it.









    Finally RedSn0w has finished loading everything onto your phone. You will see a pretty screen on your phone as it is being Jailbroken. Don't mess with your phone will all this is going on. After your phone restarts you are done!

      Thank you! thank you! Thank you! this worked first time I tried it and worked flawlessly Cheers to dev team from all of us who don't know squat about software programs. Cydia works great for me, it seems like it might be a little slow, but that could be from all people on the system.

      I'm having a different problem. I get through the redsnow program fine but once the phone goes to the "downloading Jailbreak Data", I get a windows message that redsnow has stopped working and to close it. I then have to power off the phone. Anyone else have this problem? I've tried re-downloading redsnow but still have the problem.

      I believe your going to have to start all over with a fresh copy of 3.0. Put in DFU mode/restore/J/B

      I have tried this now over a dozen times (maybe more) the phone goes into DFU mode and I always end up with the same result.

      Anyone having issues with the status bar disappearing when you open some applications? I'll go back to my home page & I can't swipe the top or see the signal, battery, etc. I have to go back into mail or another application for it to show back up.

      Your thoughts are appreciated

      @ OnlyOneSmoke - you have to save the file with ".ipsw" at the end and of as a ".zip" file. It took me awhile to figure it out b/c I unzipped & it was just .dmg & other files. If you go back several pages in this thread it's explained.

      On the first post in this thread. Download to your desktop, easier to locate them that way.

      Question, Do you back up everyting again if you are doing a restore of the 3.0 or can you just update to 3.0. Backup takes forrrrrever!!!
